Eh? I don't have the manual with mine, but 2x27128 shouldn't be a problem,

-----------------
The manual has pretty clear instructions for changing the baud rate, up to
19.2 (pp. 8&9); you'll need 2x27128 unless you have a second programmer. I have the 8052-BASIC based one that Steve
Ciarcia had in an article in
Byte, and that uses a serial connection. Only at 1200 baud, though,
for some reason.
4K doesn't take _that_ long to push over 1200 bps... Hmm. I wasn't thinking PET as much as C64, when
I wrote that. The ROMs
in that one were all 24-pin parts, a 4K character rom and the BASIC and
Kernal being 8K, which would need a 2764.
See MCM68764 & MCM68766 (24 pin 8Kx8)
I wasn't aware of these. Though I suppose I'd still need an adapter, for the
programmer? I'll look for some data on them.
